Application led November 26, 1917. Serial No. 203,916. i i

To all whom it may concern:

Be it known that I, JOSEPH LEMAY, a subject of the King of GreatBritain, residing at, Sault Ste. Marie, Province of Ontario, Canada,have invented certain new and use ful Improvements in Coal-Pushers; andIV do hereby declare that the following isa full, clear, and exactdescription ofthe invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The present invention relates to an automatic fuel feeding or ejectingdevice to be used in connection with locomotives, and an object of thepresent invention is to pro-` vide an ejecting` device of this characterwhich may he carried by the tender of the locomotive whereby the fuelmay be properly fed in front of thellire box of the locomotive, so thatthe fireman will haveat all times the proper amount of coal in his reachfor feeding` the lire box of the locomotive. y

With the above and other objects in view which will hereinafter appearas the descripl tion continues, the invention consists of the novelfeatures of construction, combination and formation of parts as will behereinafter more fully described and particularly pointed out in theappended claims.

In the accompanying drawings has been shown the simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details herein exhibited,but the right is hereby reserved to any changes, alterations ormodifications to which recourse may be had that come within the scope ofthe claims without departing from the spirit of the invention orsacrificing the efficiency of the same.

In the accompanying` drawings:

Figure l is a vertical section through the device embodying the presentinvention showing the operating lever in one position; and,

Fig. 2 is a similar view showing the operating lever in anotherposition.

Referring now more particularly to the accompanying drawings whereinlike and corresponding parts are designated by similar referencecharacters throughout the sev eral views,

The device as herein shown comprises a` bin through the opening 6 uponthe plat` form 6, whereby theproper amount of coal `will he in readyaccess of the fireman. The

feeding mechanism as herein shown com prises a rack bar 7 which extendsthrough an openinpformed within the partition 4, passes t rough theguidways formed within the support 8 and one end of this bar 7 isprovided with a piston head 9 which is mounted for reciprocatingmovement in the bin 5 so that the coal may beforced from said` bin.Journaled within the bearings 10 carried by the support 8 is a shaft 11upon which is mounted a manually operating handle 12. Pivotallyconnected to one face of this lever 12 are the pawls 13 and 14:respectively. The smaller pawl 141- being connected to the lower end ofthe lever 12, whereas the longer pawl 13 is connected to the lever l2 atthe upper side of its connection to the shaft 11 and both of thesepawlsY are adapted to engage the teeth of the rack bar 7. Also pivotallyconnected to the inner face of the partition l is a pawl 15 adapted toengage the teeth of the rack ban 7.

From the foregoing it is obvious that when the lever 12 is forced in itsforward direetion as shown in Fig. 1 the pawl 13 will engage one of theteeth of the rack bar and cause the rack bar to move a slight distanceand upon the rearward motion of this lever 12 as shown in Fig. 2 thepawl 111 will engage one of the teeth of the rack bar and still move therack bar another notch forward and likewise through the continualreciprocation of the lever 12 the rack bar will be intermittently movedin a forward direction so that the piston 9 will force the coalgradually from the bin 5. The pawl 15 will prevent the rack bar 7 fromYmoving in a rearward direction, but in filling the bin 5 with a newsupply of coal the pawl 15 may be raised and the lever 12 swung upon itspivoted connection so that the pawls 13 and 141 will be out ofengagement with the rack bar 7y and in this way the piston may be movedin a rearward direction so that the bin may he again supplied with coal.Arranged within the base l below the bin 5 are a plurality of heatingcoils 16 which may be supplied with hot water or steam so that the coalwithin the bin 5 may be heated to prevent the same from freezing, whichwould prevent the ready removal of the coal from the bin 5.

within said storing bin, a rack bar connected vto said piston, apivotally mounted lever, and

pawls carried by said lever for engaging the teeth Vof said rack barwhereby upon the reciprocating movement of said lever said rack bar willbe moved intermittently in a for- Ward direction.

2. In a coal feeding device of the character described the combinationwith a supply bin, a piston mounted therein for reciproeating movement,a rack bar secured to said Copies of this patent may be obtained for Itis also obviousthat instead'of the lever piston, a pivotally mountedpuwl for engaging the teeth of said rack bar, a pivotally mounted lever,a pair of puwls pivotally connected to said lever and arranged one ateach side of its pivoted connection, said pawls adapted to engage theteeth of said rack bar whereby upon the reciprocating movement of saidlever said piston will be cause-d to move in a. forward direction.

8. In a coal feeding device the combination with a supply bin,comprising a pair of end walls, one of the end Walls having uy dischargeopening, a. piston mounted for reciprocating movement within said bin, arack bar connected to said piston and extending through the other ofsaid end walls, a pivotally mounted pawl carried by one of said endwalls and adapted to engage the teeth of said rack bar, means forintermittently moving' Said rack bar in a forward direction, and heatingcoils arranged below said bin Substantially as and for the purposespecified.

In witness whereof I have hereunto set my hand.

JOSEPH LEMAY. In the presence of- ETHEL HUGILL, IRENE TORAN.
